Product Types • In Draft 1, EPA proposed revised definitions based on pixel

density where: – >5,000 pixels/in2 is a Monitor; and – ≤5,000 pixels/in2 is Signage

• Stakeholders commented that certain Signage, for example those with UHD resolution, could have >5,000 pixels/in2

• In Draft 2, EPA is proposing a set of quantitative criteria to classify Monitors and Signage Displays including – Size; – Pixel Density; and – Luminance

11

Product Types • EPA is proposing the following language in Draft 2:

a) Monitor: An electronic display intended for one person to view in a desk based

environment.

b) Signage Display: An electronic display intended for multiple people to view in

non-desk based environments, such as retail or department stores,

restaurants, museums, hotels, outdoor venues, airports, conference rooms or

classrooms. For the purposes of this specification, a display shall be classified

as a signage display if it meets two or more criteria listed below:

(1)Diagonal screen size is greater than 30 inches; (2)Maximum Reported Luminance is greater than 400 candelas per

square meter; or (3)Pixel density is less than or equal to 5,000 pixels per square

inch.

12

6

5/12/2015

Product Types • EPA is also considering additional qualitative criteria to

distinguish Signage from Monitors, such as: – Designed for wall installation or mounting on a stand – Ability to perform scaling for use in video walls; – Unique addressing; – Remote-control disabling; – Vertical and horizontal orientation; – Continuous use; and – Networking

13

Color Gamut • EPA received feedback that reporting of color gamut under

Version 6.0 is inconsistent, making it difficult to compare performance – Some models are reported in the NSTC space – Other models are reported in terms of sRGB and Adobe®

• In Draft 2, EPA proposes:

3) Color Gamut: Color gamut area shall be reported in the CIE 1976 u' v' color space per Section 5.18 Gamut Area of the Information Display Measurements Standard Version 1.03.

14

7

5/12/2015

Color Gamut • CIE 1976 (a.k.a. CIELUV or u’ v’) beneficial

because it contains all perceptible colors and it is larger than the largest implementation of color management (ProPhoto).

• Use of CIELAB (a.k.a. CIE 1976 L*a*b*) and its 1994/2000 updates (typically denoted as CIE D50 in color matching profiles) is becoming more popular.

15

Plug-In Module • EPA has revised the Draft 1 definition of “Internal

Processor” to “Plug-in Module” – Focuses on add-on modularity/plug-in enhancements for

either rendering images or processing touch signals – Intended to exclude any processing capability that might meet

the threshold of a computer for general computing including devices covered under the ENERGY STAR Program for Computers

16

8

5/12/2015

Plug-In Module • EPA is proposing the following language in Draft 2:

5) Plug-in Module: A modular plugin device that provides one or more of

the following functions without the explicit purpose of providing general

computing function:

a) Display images, mirror remote content streamed to it, or otherwise render content on the screen from local or remote sources; or b) Process touch signals.

Note: Modules providing additional input options are not considered Plug-in Modules for the purposes of this specification.

17

Power Management

• In response to Draft 1, one stakeholder suggested the automatic power down time be revised from 15 minutes to 5 minutes which: – Is likely to have little impact on user experience; – Saves energy

iv. Monitors shall automatically enter Sleep Mode or Off Mode within

5 minutes of being disconnected from a host computer.

Monitors Draft 1 On Mode Requirements

• In Draft 1, EPA proposed a single asymptotic On Mode Power requirement line w/ Area and Resolution – Accounts for flat component efficiency at larger screen sizes – Provides a cap on total power – Allows for fine adjustment and consistent approach across

the size bins – Stakeholders were generally in agreement with this approach

Product Type PON Max (watts)

Where: A = Viewable screen area in in2 r = Total screen resolution in megapixels

5/12/2015

Total Energy Consumption (TEC) Overview • In Draft 1, EPA proposed the TEC approach and has

now incorporated it into Draft 2 for Monitors only – As new features and functionality come into the market and

are enabled during Sleep Mode, allows for flexibility while still continuing to drive efficiency

– Reduces the need to have a large number of relatively small sleep allowances

– Lessens the criticality of the actual adder values for the ones that are included

– EPA would continue to require reporting of On, Sleep, and Off Mode power levels, but the requirement for On and Sleep would be expressed in kWh per year

25

Modal Assumptions • Based on Computer modal assumptions – the time

spent in On Mode corresponds to Computer Short Idle: 35% in On Mode, 65% in Sleep Mode

Short Idle: The mode where the Computer has reached an Idle condition (i.e., 5 minutes after OS boot or after completing an active workload or after resuming from Sleep Mode), the screen is on, and Long Idle power management features have not engaged (e.g. HDD is spinning and the Computer is prevented from entering sleep mode).

26

13

5/12/2015

Modal to TEC Conversion • Power in On Mode and Sleep Mode is converted to TEC:

– On Mode: 35% x 365 days/year x 24 hr/day = 3,066 hr/year – Sleep Mode: 65% x 365 days/year x 24 hr/day = 5,694 hr/year

• Example Calculation for a typical Monitor: ETEC ൌ 8.76 ൈ 0.35 ൈ 19W 0.65 ൈ 0.3W ൌ 8.76 ൈ 6.65 0.195

ൌ 60kWh/yr 27

Modal to TEC Conversion • The resolution allowance is calculated as follows:

– 2.0 W per Total Native Resolution (Megapixel) in On Mode

– (2.0 W/MP x 3,066 hours)/1000 = 6.13 kWh/Megapixel

• The overall Maximum TEC equation was adjusted to recognize a similar percentage of models as the Draft 1 On Mode Criteria

Version 6.0 Characteristics of Enhanced Performance Displays (EPDs)

Contrast ratio of at least 60:1 at

horizontal viewing angles of at least 85

degrees

Total Native Resolution greater than or equal to 2.3 megapixels (MP)

Color gamut of at least sRGB

(IEC 61699 2 1)

• In response to Draft 1, stakeholders commented that: – A majority of the market meets sRGB, so

Adobe RGB should be the criterion – Models over 27 inches are typically

higher-end, with better luminance and color performance

– Draft 1 30% allowance is insufficient for AdobeRGB

Enhanced Performance Displays • EPA reviewed the dataset to identify models that offered

color performance above 100% sRGB – Set a minimum of 96% of Adobe to create a higher

performance bin (10 models based on Version 6.0 data)

Models with ≥96% Adobe Color Space

Further Enhanced Performance Allowance Modifications • To align the pass rate of EPDs with monitors as a whole,

EPA is considering: – Reducing the allowances for ≥99%sRGB and especially

96% Adobe RGB – Excluding the resolution allowance before applying the EPD

allowance:

Enhanced Performance Questions • Is there underreporting of models that meet EPD criteria in

the Version 6.0 dataset? Many non-EPD models appear to meet ≥99% sRGB

• Is contrast ratio of 60:1 at 85° horizontal viewing angle still representative of high performance?

• Which delineation for Adobe performance is appropriate? 96%, 99%, 100%... other attributes to consider? What will be the post Adobe color space in common use?

• Should color or luminance uniformity be taken into consideration?

• Are there differences in enhanced performance features between models intended for home entertainment versus for professional image production? In other words, will there be EPD for the home/hobbyist market?

47

Monitor ABC Incentive • EPA is maintaining the Draft 1 ABC proposal

48

24

5/12/2015

Monitor Ambient Light Conditions • EPA seeks more data on the ambient light settings where

Monitors typically operate – In particular: office and home conditions

• 23 ENERGY STAR certified models tested with ABC – 47% average difference between 300 lux and 10 lux

49

Sleep Mode • In Draft 1, EPA proposed the following Sleep Mode

Allowance revisions:

25

5/12/2015

Connected Sleep Mode Data • Existing data show bridging and network function are

well below current V6 allowances – Small difference between connected and non-connected

51

Sleep Mode • In Draft 2, EPA is proposing to only provide a TEC

allowance for Full Network Connectivity if full network connectivity demonstrated using the test method

• The Draft 1 0.5 W allowance for Full Network Connectivity in Sleep Mode has been converted to 2.9 kWh/year in the TEC allowance

52

26

 

5/12/2015

Full Network Connectivity • Version 6.0 data does not confirm whether the model

supports Full Network Connectivity – The allowance was not used in the TEC pass rate

analysis • EPA is proposing allowance based on

– Network-connected desktops and imaging equipment can Sleep with Wake-On-LAN below 2 W

– Sep 2013 IEA 4E Standby Power Annex report “Power Requirements for Functions” notes the following power for requirements for efficient networking :

53

Ac-dc Loss Conversion Factors • EPA is proposing a 85% efficiency conversion factor for dc

powered displays – Accounts for losses at the computer power supply and dc-dc

conversions in the connected computer to permit a fair comparison with ac-powered Displays

– Based on ENERGY STAR certified computer data – Applying On Mode efficiency conversion for TEC

• EPA did not receive significant comment on the Draft 1 proposal

Monitor Mode Typical Computer Load Factor

On Mode 30% 85% Sleep Mode 6% 81%

61

Signage Displays Luminance • EPA corrected the luminance power allowance in watts to

the following calculation:

7.5 ൈ 10ିହ ൈ ℓ ൈ ܣ – Luminance is Maximum Measured Luminance of the

display in candelas per square meter, as measured in Section 6.2 of the test method

– Area is Screen Area in square inches – Uses only measured values as reported per the test method

– the 7.5 x 10-5 factor takes into the inches to meters conversion
